TREE-NAIL MACHINE.

ASpecification of Letters Patent No. 12,909, dated May 2.2, 1855.

T0 all whom it may concern:

Be it known that I, I. IV. HOAGLAND, of Jersey City, county of Hudson,and State of New Jersey, have invented a new and useful Improvement inthe Machine for Making Tree-Fails; and I hereby declare that thefollowing is a full and exact description.

To enable others to make and use my invention I proceed to describe itsconstruct-ion and operation, reference being had to the drawingshereunto annexed'and making part of this specification.

The machine as shown in the drawings is -set upon a frame or bench so asto bring it to a convenient height, and may be driven by a one horsepower. The head pieces and other stanchions are of cast iron and theshafts of wrought iron.

supposing the machine intended to form an Octagon treenail there will beeight shaftsa as shown in the side elevation and marked These are allconnected by cog wheels. The driving pulley is upon one of these eightshafts at the rear end of the machine, Fig. 4.

The bolt or stick of which the treenail, (X), is to be made is enteredbetween the two feeding rollers (see Fig. 1) which are set front of andoutside the cutters. The stick-is acted on by the cutters and shaped atits end and thus received by the second pair of feeding rollers (seeFig. t). These are held with considerable pressure upon the treenail'.The pressure is however gaged and governed by the oval button (b and R)Fig. 2 and this is moved and governed by the levers The front head (A)in which the shafts of the cutters run isabout fifteen inches indiameter, of a circular form and about two inches thick. In the rearside of this casting depressions are left in which sit the turned true,about half an inch in diaineter.

This protrudes through the slot in the circular plate D. The circularplate is wrought iron about three eighths of an inch thick and the rimtwo inches wide. This circular plate has bolted to it, two arms orlevers (D). The rear side of the head is turned out so that the circularplate will fit into it snug and yet admit of its turning a little.

Upon the side of the machine is a wheel, J, about eight inches indiameter, having pins or cogs upon its periphery on which runs a chainband (w) to which a weight is att-ached. Upon the same shaft is a smallpinion, K, working into a horizontal rack which lies upon it. Upon thisrack, T, is laid the gage or pattern formof the tree* nail, cut from astrip or iron, and marked U. In the center of the machine is a rod, onthe forward end of which is a circular disk, called the follower (I-I)which is supported by projecting arms upon a track or way, Z, upon eachside of the machine. Upon the rod is an arm to which the chain band isattached-so that when the follower is thrust back by the treenailstriking against it, it will turn the wheel (J) over which it runs andwhen the treenail drops the weight will .draw the follower back againtoward the head of the machine.

Upon one of the arms D is screwed a 'perpendicular stem (Y) with a slotat its fastening so that it can be graduated. At the bottom of the stemis an anti-friction roller and this rests upon the pattern, U,

hinged upon a cross piece on the stanchion see Fig. (2) and upon theinner side of it is screwed a lever (R) which rests against the arm D ofthe circular plate and is governed by its motion. There is an ovalbutton, b, on each side, and the lever attached is, on one side, placedabove the arm D of the circular plate and on the other side beneath it.lVhen'the gage or pattern causes a mot-ion of the arm of the circularplate it moves also the levers R upon the oval button and these forceapart the boxes of the feed roller shaft and the spiral springs forcethem together again. Thus accommodating the opening of the feed rollersto the varying size of the treenail.

The feed rollers are driven by a pinion P upon the top shaft about threeinches diameter. This meshes in a ten or twelve inch cog wheel O, upon ashaft, N, running to the forward end, where it has a small bevel pinionworked in a large one M which is on the upper feed roller shaft. The twopairs of feed rollers are connected by gearing, L.

I/Vhen the treenail is finished it is made to drop out by means of atreadle. In which I do not claim novelty and therefore it is notrepresented.

On the rear end of same two of the shafts I screw on collars in whichthere is, in each a conical hole, with knives set in and screwed fastlike plane irons, having openings for the chips like the throat of aplane. This is for pointing and heading the tree` nails. One being mademore flaring for the head and the other shaped for vthe point. While themachine is in operation and these shafts revolving with great rapidity.The treenails are received as they fall from the machine and the endsthrust in at these conical holes and thus instantly rounded at the headand sharpened at the point. This saves the treenail driven from thenecessity of sharpening them with the broad axe as usual and therounding of the head prevents its splitting when driven. See Figs. 12,13, 14, and 15 for the heading and sharpening collar. A screw is set atthe bottom to gage the depth at which the head or point shall be thrustin.

In the attachment of the cutters there is nothing new. They are screwedto the forward ends of the shafts. The formation of the cutter-see Fig,11 is new. It is bent, as in .former machines, but then twisted or madediagonal, so that it will cut at an angle.

The improvements which I have made produce the following advantages. Thegage U is moved by the follower IFI and that is moved by the tree nailwhich is in process of formation and the tree nail is made exactly tothe pattern. The tree nail in my improvement is held firm by the feedrollers and does not shake. The button on the lever It, opens them toadmit the tree nail as it is enlarged. The circular plate holds theboxes solid and by its movement gages the size of the tree nail-the arm,D, being raised or depressed by the pattern, U, passing back and forth.I head and point the tree nail as fast as made, and in this machine I dono-t require to shave the bolt or stick, but enter it in the rough andmake a perfect tree nail at one operation.

What I claim as my invention and desire to secure by Letters Patent is:

1. The use and employment of the circular plate (B) with its diagonalslots (a) to concentrate or expand the cutters and thus regulate thesize of the tree nail in the manner above described.

2. The use and employment of the follower (I-I) with its apparatus ofband and wheel to govern the gage, U, so that the tree nails may be madeuniform in size; arranged and constructed substantially as abovedescribed.

3. The use of the levers and their apparatus of ovals (5,) to separatethev feed rollers or allow them to approach each other, for the purposeof holding the tree nail firmly, while it is being enlarged ordiminished, in the manner above shown.

4.. The use of the pattern gage (U) and the stem (Y,) to govern thecircular plate.
